how much money do you have to spend? what charger are you going to buy. Basically, I bought a turnigy accucel digital 6 without powersupply and used my laptop charger however my laptop charger is one that has all these different connectors. Will find it for you and edit it in

thats it, for my power supply all I needed was the standard connector that you could use to connect the other connectors on to. Its good because it doesn't get very hot and you can adjust the voltage.
